How do *Bipes biporus* achieve locomotion underground without relying on typical lizard walking patterns?

Answer

They use muscular contractions to 'inch' forward underground

Since *Bipes biporus* lacks the typical legs for standard terrestrial locomotion, its movement underground relies on powerful, serpentine muscular contractions. These contractions allow the animal to effectively 'inch' forward through the soil matrix. The two specialized forelimbs function more as anchors or tiny shovels, providing purchase and stability against the soil as the rest of the body propels itself forward, a motion that allows efficient movement within the dense, confined space of their tunnels.
